Kidney Disease

KidneysNormal, healthy kidneys filter about 200 quarts of blood each day, generating about 2 quarts of excess fluid, salts, and waste products that are excreted as urine. Loss of function of these organs, even for a short period of time or due to gradual deterioration, can result in life-threatening complications. Whether kidney function is lost suddenly or slowly represents an important health challenge.

The NIDDK supports basic and clinical research on kidney development and disease, including the causes of kidney disease; the underlying mechanisms leading to progression of kidney disease; and the identification and testing of possible treatments to prevent development or halt progression of kidney disease. Also of interest are studies of inherited diseases such as polycystic kidney disease, congenital kidney disorders, and immune-related kidney diseases such as IgA nephropathy and hemolytic uremic syndrome.

It has been estimated that more than 30 million American adults have chronic kidney disease (CKD). CKD has two main causes: high blood pressure and diabetes. CKD, especially if undetected, can progress to irreversible kidney failure. People with kidney failure require dialysis or a kidney transplant to live. Minority populations, particularly African Americans, Hispanic and Latino Americans, and American Indians and Alaska Natives, bear a disproportionate burden of CKD and kidney failure.

In addition, NIDDK received congressional authorization for the National Kidney and Urologic Diseases Information Clearinghouse. The Clearinghouse provides public inquiry response services and health information about kidney disease to people with kidney disease and to their families, health professionals, and the public. The National Kidney Disease Education Program (NKDEP) aims to reduce the morbidity and mortality associated with kidney disease by promoting evidence-based interventions to improve understanding, detection, and management of kidney disease.

Conduct Research

NIDDK investigators conduct biomedical research and training in the Institute's laboratories and clinical facilities in Maryland and Arizona.
